Given physical quantities and laws relating these quantities, identify an answer where the graph which relates these quantities is a part of a parabola. (The other quantities are supposed to be constant.)
The electrical work (W) and the current (I), if W=R⋅I2⋅t.
The mass (m) and the acceleration (a) of a moving body, if F=m⋅a.
The height (h) and the potential energy (Ep), if Ep=m⋅g⋅h.
The electrical work (W) and the time (t), if W=R⋅I2⋅t.
